Supratek Owners Thread

Greetings All - 
It appears that the 26-million-plus view, multi-decade "Preamp Deal of the Century" Supratek thread has been removed. I'm not sure why, but suppose there must be a reasonable explanation.
In any case, on that thread I recently asked whether there might be interest in a "Supratek owners thread" and received some interest. 
The purpose of this thread is for Supratek owners to share the details of their system, ask questions, share information about any tube-rolling they have done, and so forth.
I'll kick us off here with a few details about my system -
ancient Linn LP12 with Ittok arm, Dynavector 17D3 cartridge into Cortese LCR phono stage
Power amp is a fully serviced Innersound Electrostatic amplifier
Quad ESL63 speakers (not USA monitors) or JBL 4430 studio monitors
Digital sources are immature and evolving - ancient Fostex CR300 cd player/burner
DacMagic 100 DAC
Nordost Blue Heaven 75ohm interconnect
Due to the fairly long lengths of speaker wire required in the new listening room, speaker wire is Belden 12 gauge wire designed for low-voltage outdoor lighting systems. 
Next steps - dedicated circuit, new power cords, new interconnects, new wires.

I`m using a LTA pre now. For me the LTA`s are a little on the cool side. And thanks everyone for the 6SN7 info.

highstream. Mick said he has been very busy during this pandemic.

The reason i decided on Supratek was not only the reviews but reading thru his blogs it became apparent that Mick and myself have the same beliefs in sound and what sounds good and what does not and the whys. And his thoughts and experience on class D amps mirrored mine to a tee.

I just got an email for a post by jeony about the Cortese and how well his tube rolling turned out, but I don’t see the post. In any case, in addition to liking the Melz 1578 the best and the Shuguang WE6SN7 Plus next, he mentions the 6922 and E108F. The latter two are not used in the Chardonnay afaik. The back pair are 6N3C. I tried the Tung-Sol 7581A as reputedly the best replacement but ending up sending them back, as I wasn’t sure one of pair was good. In addition, Mick made clear that he doesn’t like the 7581 and didn’t think the regulator works correctly with it. Has anyone had a different experience back there?
